The song "The Coldest Sea" by Joseph Arthur talks about the experience of being a refugee and the lasting impact it has on a person. The lyrics suggest that the protagonist has always been a refugee, constantly moving and never feeling settled. Despite growing older, there is a lingering feeling of displacement in their heart. The song asks the protagonist to share their past experiences, particularly swimming in the coldest sea. This metaphor represents the hardships and challenges the refugee has faced throughout their life. The lyrics also suggest that the protagonist may have suppressed these memories, asking if they can open up their heart to a world that has caused them pain and torn them apart. The line "And you always follow everyone, never wanting to stand by" suggests that the protagonist tends to go along with others instead of asserting their own identity, possibly as a result of their refugee status. The lyrics imply that running away and seeking love has been a coping mechanism for them. The song asks the protagonist once again to share their experiences, highlighting the need for them to confront and embrace their past. Ultimately, it becomes a plea for the protagonist to open up their heart to a world that has caused them pain, with hopes of healing and acceptance. Overall, "The Coldest Sea" reflects on the struggles and emotional turmoil of being a refugee, the longing for connection, and the internal battle to reconcile with one's past.
